Benefits of technology

The invention provides a pouch that can be used with different viscosity fluids. It includes a flexible valve and an orifice that work together to control the flow of the fluid. The stiffness parameters of the valve can be adjusted to accommodate different products. The pouch is easy to use, and when the force to bend the valve sections is removed, they return to their original position and close the opening in the pouch. This invention allows for more efficient and flexible use of pouches for fluid discharge.

Problems solved by technology

It becomes more difficult to control the amount of low viscosity products exiting the pouch because the valve sections require a relatively weak force to bend outwardly with these products.

Abstract

The present invention is directed to fluid-dispensing flexible pouches having at least a first wall portion, a second wall portion and a means to manually discharge a fluid product from inside the pouch. The means to manually discharge a fluid from inside the pouch comprises an orifice formed in either one of the first or second wall portions or a patch, and a flexible self-sealing dispensing valve having at least two intersecting lines of weakness formed in either one of the first or second wall portions or the patch.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to primary packaging for fluid or viscous products and the like, and in particular to pouches having a flexible self-sealing dispensing valve.[0002]Many different types of packages or containers are presently available for packaging non-solid products of the type which are capable of flowing, such as fluid or fluidized materials, including liquids, pastes, powders, and the like, which substances are collectively and generically referred to herein as “fluids”. Fluid material also includes viscous food products like pancake batter, syrups and various types of condiments that include mayonnaise, guacamole, ketchup and mustard. Such foods are often provided to restaurants and food service providers in rigid or flexible plastic tubes. Some such packages include a dispenser which permits a selected amount of fluid to be discharged from the package, and then reseals to close the package. Typically, these self-sealing ...
